I'm working on a "What is the statistically fastest way to fuse a Mythic" guide. This FuseBuddy will be handy.

Much like there are pieces of equipment, when attached to specific heroes in specific party configurations, yield extremely powerful results-- I think there may be a series of pre-fusions that may yield fast fusion results. Time is the mitigating factor in fusions. It will be a lot of input and output recording.

Is it faster to (10) [(1) Level 40 Common + (1) 40 Flawless] fusion to get Epics to fuse into Legendaries, or do you get more level 40 Epics and Legendaries faster by fusing (10) [(4) Level 25 Epics with (1) Level 40 Flawless] items in the same amount of time? That sort of theory crafting. Or maybe level 20 Epics. Or level 15 Epics. There's so much entry and recording, and it's so slow. ><
